- In order to track the perspective of the sand areawe can attach our title to the video by using mocha AE.By doing that we'll be able to analyzethe surface of the sand and its perspective,and the result will be an accurate corner pin datathat we can simply copy and paste between both softwares.As I mentioned in order to track this outwe are going to use the built-in version of mocha AEwhich ships with After Effects.Now, believe me that I've tried other methodsof tracking this here inside After Effects,and also trying to solve the camerausing the 3D Track Camera option inside After Effects.

None of them yield the desired result.Here I'm just offering youwhat I think will be the best choice.But each footage is different,and you should also examine a couple of solutions.Most people feel more comfortable not leaving After Effects,but I promise you that what we are about to doinside mocha is very fast and not painful at all.I'm going to walk you through the steps.We actually need to track the video footagebecause the data that we're going to collectis going to be applied to the title,meaning that the title at the end should stickto this sand area over here that we are seeing in the video.

I'm going to select the clip itself,and then the only way that you can launch mochais go into the Animation menu and ask After Effectsto track it inside mocha AE.This will launch mocha AE from After Effectsand it will switch you to the interface of mocha.Now, if this is the first time that you open the softwareyou might need to register itor also ask what to see in the beginning,meaning to define the preferences.

Also decide if you want to seethe opening splash screen or not.I of course dismissed it in this casebut if you see something else when you are following meand, of course, this will only happen if this isthe first time you are launching the softwarethen just go ahead.Read through these menus and basically approve them.Now you should reach to this point whenit will ask you where to save that new project.By default it will save it near the source file itself.Anyhow, let's click OK over hereand this will load the same clip with the same in and outof the same range that you've decided inside After Effects.

In our case it will take the whole frame.Now I'm just going to scroll.I need to find the best place to start tracking.I'm going to choose the x-spline tooland I'm going to create this shape.One click over here.One over there.Maybe somewhere over here.And then over here.If you want to close the shape,right click on it and mocha will close it for you.Now, I'm just going to stretch these pins,and those pins doesn't have to respectthe perspective of the shot.

You just need to define an area with enough details.What I'm trying to achieve here is an areawhich is not going to be abstracted by the car.In this case I may want to take this pointand just move it a little bit down.Same is true for the upper one.I just don't want the car to distract the tracker.This is what I'm checking here.If you are working with more complicated shotwell then, of course, you can drag your cursorand create keyframes for this shapebefore even starting the truck.

But I think that we are okay over hereso I'm just going to go back to this green framewhich is the frame that I used toin order to draw this shape.First let's track forward.Click on this right triangle and let mocha think about it.It shouldn't be too complicated becausethere is not a lot of movement from this point onward.Now, let's take our cursor,bring it back to this point,and then let's track backwards.Most chances if you defined an area with enough detailsis that mocha will do an excellent job.

You do need to watch it.You do need to make sure that nothing is going tojump or disappear.But as expected mocha will probablydeliver a very accurate result.We are going to speed up the recording,so you don't have to sit here and watch mocha do its thing.Once it's finished you can drag along to check the result.Now we'll need to actually define the corner pins.Press on this little s-planar surfaceand then just take those four cornersand try to imagine how the title will look.

Now you need to actually put it whereyou want the title to appear.Now in this case I do want the title to appearat least partly under the wheels of this jeep.I'm going to take this and just drag it maybe over hereand then I'm going to compensate something like thisin order to make sure that when I'm exporting this datasome of the text will be underneath the wheels.In order to illustrate their resultsa little bit more clearer you can insert a clip.

You can either render a freeze frame of your logoor use the built-in mocha logo by selecting it from here.Now it's getting a little bit crowded and difficult to seebecause all of the overlays.I'm just going to turn them off momentarilyand then go to the beginningand just play the result to try and judge if this looks goodor should we fix it.To my eyes it looks very well.It sticks to the floor,and the perspective of the logo looks quite believable.

I'm just going to stop the playback.Then I need to export the tracking data.Now in this case just note that our motion was large motionand we didn't analyze the perspective.But if you do have cases wherethe perspective in the shot is changingusually when you are trying to trackcomputer screens or bus signage, you can't turn it on.But in this case it is not required.Now we are ready to export the tracking dataand see how it performs inside After Effects.

We actually finished with mocha not beforewe are going to click on the Export Tracking Data.Then make sure to select the middle option,the After Effects Corner Pin with support for motion blur.I'm going to Copy to Clipboardand then I'm going to switch back to After Effects.Now I need to make sure thatwhen I'm pasting this informationmy cursor will be at the beginning of this composition.This is a very important step.Then select the text and go to the Edit menuand just choose Paste.

Now it looks like something went completely wrong.Although we saw a great result when we used it inside mochathe tracking information didn't translate well.I'll show you how to fix it in the next movie.
